Dodge County Sheriff Jim Jensen says dental records have confirmed the body found Thursday near Kasson was the Byron teenager who was reported missing in late January. The remains of 15-year-old Noah Graddy were discovered just east of Kasson by law enforcement officers involved in a search for the missing teenager. Sheriff Jensen says an autopsy did not find any evidence of trauma to the body and investigators are confident his death was not due to homicidal violence. The cause of his death remains under investigation.
